PAPER BEGEPTACLE OR CONTAIN ER AND ART OF MAKING THE SAME.

Original application filed January 24, 1920, Serial No. 353,692. Dividedand this application filed November 24, 1922.

This invention relates to receptacles or ,contamers made by windingpaper or other suitable material on a form or maninner ribs whlch areformed on the inside of the container in the course of winding the stripon the mandrel. These ribs, constituting seats for the closures, areformed by, or reinforced by, strips of metal or other materialofsuitable strength, which are introduced into the wall of the tubeasthe winding proceeds and are wound into place with the paper whichforms the wall. To this and other ends the invention consists in thenovel features hereinafter described.

Referring to the accompanying drawing, Fig. 1 is a sectional elevationof one form of my improved container. For the sake of clearness, inorder to show the reinforcing strips as plainly as possible, the severalplies or layers of papers composmg the wall oil the container are notindicated.

' Fig. 9 is a sectional view of a form of the invention in which groovesare provided on the outside of the container wall, corresponding to-theribs on the inside, to receive reinforcing bands;

Fig. 10 is a detail sectional view showing a convenient method ofsecuring a head removably in place.

My improved container may be of any suitable shape in cross section, forexample circular, oval, elliptical, or polygonal, but

the circular cross section is in general stronger and is thereforepreferred, especially for barrels or drums of large capacity. ln Figs. 1and2 a container 10 of the cylin drical type is shown, having closuresor heads 11, 12, which are held by or against inner circumferentialseats consisting of beads or ribs 13, 14:, 15, 16, reinforced bysimilarly ribbed or corrugated strips of sheet metal l7, 18. Asexplained hereinafter, these metal strips are wound into the wall of thecontainer as the tubular body is formed, the strips being thus embeddedin the wall. lnstead of sheet metal, the ribs may be reinforced by wiresof suitable cross section, as round wires 19, 20, Fig. 3, or trianlarwires Fig. 3. If one head is to be permanently secured in place I preferto use three beads, as in Figs. 1, 2 and 3,- an upper bead 1d and lowerbead 16 embracand an intermediate or middle bead 15 en-' gaging a groovein the edge of the head, but one or more of these beads may be omitted.Thus in Fig. l the middle bead is omitted, in Fig. l the middle beadalone is used, and in Fig. 1 only the lower bead is used. In y case,especiall where only one bead is used, additional 'astening means may beemployed, as for example screws, as indicated in Fig. 1, connecting thehead and wall in any convenient and suitable manner, and the removablehead (in general the head which is secured in place after the tubularbody oil the container is removed from the mandrel) can be secured inthe same or any other way, as by means of a hoop or ring (not shown)inside of the chime and fastened thereto.

The reinforcing members 17, 18 may, if desired, be of perforated orforaminous sheet metal, as in Fig. 6, in which case the adhesive used tocement the turns or layers of paper together penetrates into the holesIOU . and at its inner end is provided with a circumferential groove 24.At its other end its edge is beveled, as at 25, and adjacent to this endis a beveled disk 26 of the same diameter as the mandrel, carried by ashaft 27. The latter is mounted in any convenient manner to permit it tobe shifted axially away from the mandrel and then be swung transverselyto permit the container to he slipped ofl axially after the mandrel iscollapsed. v The head which is to be permanently secured in place isarranged concentrically between the disk 26 and the end of the mandreland is held frictionally by the firm pressure of the disk. The head anddisk thus form in effect a part of the mandrel.

At each end of the mandrel I provide one or more roller heads, as 28,29, movable radially toward and from the mandrel, and each carrying oneor more ribbing 'or finish- 1 ing rollers, as 32, 33, 34. As the paper36 (under slight tension) is wound on, the roller heads are advanced (asby means of springs, compressed a1r, or other means, not

. shown) and the rollers are caused to bear on the surface. In thisoperation the cylindric'al rollers 33 hold the paper in snug conformitywith the surface of the mandrel, while the ribbing rollers 34, whichhave their edges beveled or otherwise suitably shaped for the purpose,indent the paper into the circumferential grooves in the mandrel. When asuflicient number of turns or la ers of paper have been wound on, therein orcing strips 17, 18 are'introduced, as in F' 4. These strips maybe just long enougdi to go once around the drum, with or without theirends overlapping, or they may be lon enough to wrap several times, andprefera 1y they are not ribbed or corrugated in advance but are fiat, inwhich case the desired ribs or beads-are formed by the bead ing rollers32, 34, while the edges of the strips are held down by the. cylindricalsmoothing or finishing rollers 33. Where both kinds of rollers arecarried by the same head, the cylindrical or finishing rollers aremounted in sliding bearin springs 38, so that such ro ers may be kept infirm contact with the paper as the wall of they tube increases inthickness. The grooves formed by the ribs) fill-upas the wlndingproceeds,v and in order to kee as fiat as possible the surfaces .next tothe ead 37 actuated by (for example the head 12, Fig. 6) the outerrollers 34 are adapted to slide axially on their shaft but are urgedinwardly toward the middle roller by springs 39;

As the winding proceeds, suitable cement, glue-or other adhesive isapplied, so that the successive layers are firmly united. Ora fusibleand waterproof material may be used, as for example paraflin; in whichcase the paper or other fabric may be impregnated in advance and thenheated as it is wound,

so that the layers will unite, cooling means being employed, ifnecessary or desirable, to facilitate hardening or setting of theparaflin.

When the wall of the tube has been builtup to the desired thickness, therotation of the mandrel is stopped. The roller-heads are then withdrawn,and the disk 26 is withdrawn axially and swung out of the way. Themandrel being collapsed, the tubular body of the container, with onehead or closure in place, can now be slipped endwise oil the mandrel.

As hereinbefore stated, the reinforcing means used is not necessarily aflatstri Other means may be used, as for examp e one or more wires, asin Fig. 3, already described. I may also use a flatstrip wide enough toreach the edge of the tube, especially if the strip is perforated, as inFig. 6, or it may be wide enough to overhang the edge at either or bothends, as indicated at 18*, F ig. 7. In the latter case, after the wallis built up to the desired thickness the overhanging portion of the strior strips is bent down upon the outer sur ace of the wall, as in Fig. 8by spinning or other suitable operation. By making the wallrelativelythin or the ribs relatively deep, or both, the tube may be left withcircumferential grooves on its outside, of greater or less depth, inwhich binding and reinforcing means may be seated, as wires 18", Fig. 9.

One or both heads may be removably secured by the method illustrated inFigs. 1 and 10. n this case the container Wall is formed with an innerbead 13 on which the head 11 rests, and with an inner circumfen entialgroove 13 to receive a split ring 13 which is sprung into the groove andoverhangs the edge of the head 11 all around. The ring may be strippedor peeled out of the groove when it is desired to remove the head. Thisgroove maybe formed over a rib 40 (Fig. 5) on the collapsible mandrel 21by means of suitable rollers (not shown) bearing on the paper and thereinforcing strips or wires as the tubular body of the container isformed; or'it may be made by cutting a groove on the inside after thebody is removed from the mandrel.

Claims to the art or method of making the container or containers arenot asserted in the present application but will be found in myapplication Serial No. 353,692, filed wardly-extendin January 24, 1920,and of which the present application is a division.
